LINE-PRINTINIG MACHINE;

SPECIFICATION forming part of Letters Patent No. 403,206, dated May 14,1889.

Application filed September 20, 1887. Serial No. 250,170. (No model.)

T0 aZZB whom it may concern:

Be it known that I, JOHN MCADAMS, of Brooklyn, in the county of Kingsand State of New York7 have invented a new and useful Improvement inLine-Printing Machines, of which the following is a specification.

I will describe in detail a line-printing machine embodying myimprovement, and then point out the novel features in claims.

In the accompanying drawings, Figure l is a side view of the portion ofa machine embodying my invention which includes theV printing andsupporting rollers and also the inking mechanism. Fig. 2 is a plan ofthe parts shown in Fig. l. Fig. 3 is a plan of a portion of anink-fountain made according to my invention; and Fig. 4 is a transversesection thereof upon about the plane of .the line x x, Fig. 3. Fig. 5 isa section lengthwise of the machine of the parts shown in Fig. 1. Fig. 6is a section, lengthwise of the machine, of an arrangement of tapes orcords and brushes whereby the paper may be cleaned as it passes to theline-printing rollers; and Fig. 7 illustrates another `arrangement oftapes and cords, including a beater and an air-blast apparatus, wherebythe paper may be similarly cleaned..

Similar letters of reference designate corresponding parts in all thefigures.

A designates the main frame of the machine, and B B' designate the pairsof line printing and supporting rollers by which the lines are printedupon opposite sides of the sheet.

O designates the feeding-apron or cords, which pass over suitablesnpporting-rollers, O' C2, and by which sheets of paper are fed from thefeeding end of the machine to the printing or ruling apparatus; and C3designates a portion of the delivery apron or cords 011 which the paperis delivered from the machine. i

In Fig. 6, which represents the feeding end of the machine, I have shownbrush-rollers or dusting-rollers D D', and two systems of endlesscordsor tapes, co b, which pass around and are suitably directed by rollersa' a2 a3 w* bf, 222 b3 b4, so as to carry the paper in contact with thebrushing or dusting rollers D D', as represented by the arrows 'in Fig.6. The dusting roller or brush D has extending below it a suitableshield, 115, which prevents the dust and scraps from falling on thepaper as it is fed along by the apron or cords O. The paper is by handfed to the cylinder or roller a' and the tapes or cords a, and iscarried around in the direction indicated by the arrows, and by whichone side is presented to the action of the brush D, and then passes onthe roller or tapes and cords b' b, by which its other side is presentedto the action of the brush D'. From the tapes or cords b the sheet isdelivered to the apron or cords O, and is by them carried forward in thedirection indicated by the arrows in Fig. 6, to the apparatus forprinting or ruling the lines thereon. p

In Fig. 7 I have shown a dusting apparatus of another form whichembodies my invention. In this apparatns the paper is fed between twoseries of cords or tapes, D2 D3,which are carried and moved by rollersD4 in the directions indicated by the arrows. Below the upperpaper-carrying portions of the tapes or cords D3 is a roller or beater,D5, of polygunder surface of the paper and fall into thev dust-pan D7.

To clean the upper surface of the paper, I employ a blast of air7 whichmay be supplied from a blower, as shown, through a pipe, D6. The paperpasses from the feeding apron or tapes C directly between the cylindersor rollers B B' of the first pair and B' B of the second pair7 and isdelivered onto the apron or cords O3, which convey it from the machine.In passing between the first pair of rollers B B' the upper surface ofthe paper is printed by the roller B, and in passing between the rollers'of the second pair its lower surface is printed with lines by theroller B. Each of the four rollers B B' has a series of disks, c, theedges of which are presented in a straight line from end to end of theroller, and which are set at a distance apart equal to the desireddistance between the lines. The disks of the rollers of each pair are soplaced that the disks of. the roller B, for example, come between thedisks of the roller B', and consequently IOO when the paper is passedbetween these two rollers the natural clasticity of the paper holds itagainst the edges of the ln'intingdisks c.

The four rollers B B ll' are intended to be intcrchangeable, so thatthey maybe used in any arrang'ement or combination, and the dislcs ofthe several rollers may be set at various distances apart to producelines on the paper at any desired distance apart.

In order to provide for readily changing` the rollers B l', so as toform different combinations of them, their journals d are supported inslotted bearings d' in the frame A, as best shown in Fig. 1,and they areprovided at opposite ends with friction-wheels e, which bear one onanother. The frictio11\\'l1eels e of the lower rollers of the two pairsbear upon corresponding` friction-wheels, E2, which are upon a shaft-,E,extending across the machine beneath the aforesaid rollers, and to whichmotion may be imparted by a driving-belt passing` over a pulley, E'.

The friction-wheels c, which are upon opposite ends of the rollers B l',are of such diameter that when the wheels at opposite ends of the upperand lower rollers of each pair are in contact the edges of the disks cof one roller will be in proper relation to those of the other roller topcrform the printing` operation, and by the frictional contact of theWheels E2 e the rollers of each pair are driven from the shaft E. Itwill therefore be seen that when the rollers are placed in anycombination their frietion-wheels e will be in contact with each other,and the wheels c upon the lower rollers will be in contact with thefrictional driving'-wl1eels E2.

F F designate the ink or color fountains, from which the upper roller Bof the first pair and the lower roller B of the second pair are suppliedwith ink or color.

G G dcsignate the two color-rollers, which rotate in the fountains, andthe j ournals of which are supported in slotted bearingsf and byantifriction Wheels I have also represented other ink or color wheels01' rollers, G', which rotate in contact with the lower roller 3' of thefirst pair and the upper roller B' of the second pair. These inking 01'color wheels or rollers G' are supplied with color by suitable feeders,g, from fountains G2, secured upon the frame of the machine. The ink orcolor rollers G' may be arrang'ed to ink or color certain of the disksof the supporting-rollers I', so as to produce on the paper head 01'other lines in a different color, as is indieated by the arrangement ofthe rollers G' in Fig. 9.

Instead of employing a separate fountain for the ink or color rollersG', which are arranged to supply ink or color to only one or two of thedis'ks which are on those rollers which serve as supporting-rollers I',I may form a divided fountain, such as I have represented in Fig's. 3and i. In those fig'ures F designates the main portion of the fountain,wherein the color-rollers G are intended to turn, and the :fountain isconstrncted with transverse partitions 71, 71/ W, thcreby forming,`compartments F' F2. The fountain also has beyond the partitions h' 71,2a supply box or compartment, F3, which is in full communication with thecompartment F' by a bridge or covered passagc, 71,3, extending throughthe compartment F2. The portion FAl of the compartment is in freecommunication with the main portion F by means of the bridge or eoveredpassage hi, which extends across' the compartment F', and color which issupplied to the main portion F and compartment Fl overtlows across thebridge h* and fills the compartment F2.

From the above description it will bc understood that the same color orink will till the compartments or portions F F2 F4, while a differentcolor or tint may be used in the compartments F' F3, which are in freecommunication by the bridge or covered passage W. By means of thisdivided fountain color wheels or rollers may be arranged to supply oneor more of the printing-disks at the end. of the printing-rollers withink of a different color or tint from that supplied to the main portionof the ink-fountain and delivered by the roller G along` the length ofthe printing'- roller.

In Fig. 2 I have 4 represented the upper printing-roller B as having' atits end an arrangement of printing-disks, c, whereby it operates, inconnection with the disks at the end of the upper supporting-roller B'to produce head-lines, and the color'roller G, for supplying the upperprinting-roller I', has color-disks G'` G3, which run in and take colorfrom the compartments F' F2 of a colorfountain like that shown in Figs.3 and i. In order to render the ink-fountains F and the ink-rollers Gself-adjusting relatively to the printing-rollers B B, I have:represented them as supported upon inclined seats 01' rests a upon theframe. They will then have a tendency to gravitate downward, which willcarry them in a direction to cause the rollers G to come into contactwith the disks or printing' or pen rollers and to maintain them in suchworking-contact. I thus dispense with any means of fastening` theink-fountains in place, and enable them and their rollers G to readilyadjust themsclves in proper position relatively to the printing-rollers.

For each inking-roller G, I employa wiper, II, which may be made ofindia-rubber, and which is approximately tangential to the roller. Thiswiper serves to remove from the roller the surplus of ink. It is held ina Suitable holder, II', which is free to slide toward and from theroller G, and to which are con? i bc employed for adjusting the holderII' toward the roller G, while the screws and. nuts IOO ITO

fi i' may serve to withdraw the wiper from the roller.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination, in a line-printing' machine, of pairs of rollers,those of each pair being' arrang'ed one above another and all providedwith disks. c, and which are interchang'eably fitted in the machine, sothat eitherv of each pair may serVe as a printing'- roller and itsCompanion as a supportingroller, and of inking` apparatus for supplyingcolor to the disks of the printing-rollers, substantially as hereindescribed.
